COLKOPTKUA. G.^ 



B. inilitare n. sp. — Rath«r depressed, robust ; black, elytra somewhat 

 piceous posteriorly, not maculate, reflection very dark metallic blackish- 

 green, elytra more alutaceous : head and prothorax very highly polished, 

 without trace of reticulation or granulation : legs rather dark rufo-testace- 

 ous ; palpi and antennae same, the latter very slightly darker toward tij) ; 

 under surface dark rufo-piceous, coxae not paler. Head moderate in size, 

 as wide as long ; eyes rather large, moderately prominent ; anterior seta 

 opposite the middle of the eye, second opposite the posterior limit of the eye ; 

 interocular surface having two longitudinal irregular and slightly convergent 

 channels, beginning slightly behind the middle of the eyes and at a short 

 distance from them ; intermediate surface ratlier strongly convex, continuing 

 with same curvature along the occiput ; labrum over four times as wide as 

 long, angles not rounded, apex broadly and feebly emarginate throughout, 

 concentric with the apical margin of the epistoma ; antennae very long and 

 slender, one-third longer than the head and prothoi-ax together, basal joint 

 moderately robust, cylindrical, equal in length to the third, second three- 

 fourths as long as the third, joints three to six almost exactly equal in length, 

 very slightly thinner toward base. Prothorax widest at one-third its length 

 from the apex, where it is distinctly wider than the head and two-fifths wider 

 than long; sides very strongly arcuate, convergent toward the base, just 

 before the basal angles distinctly sinuate ; basal angles slightly obtuse, but 

 not rounded, apical strongly obtuse and slightly rounded ; base feebly 

 arcuate, except near the basal angle, where it is straight, five-sixths as long 

 as the apex, which is very broadly and feebly emarginate throughout, almost 

 straight ; disk moderately convex, edges narrowly reflexed ; setae as in 

 vernula; median line narrow, distinct, continuous throughout the length; 

 basal depressions broadly, strongly, and irregularly impressed; cariuae very 

 short, not attaining the basal angles. Elytra widest at the middle, where 

 they are two-fifths wider than the pronotum ; sides strongly arcuate ; humeri 

 very broadly rounded, continuous in curvature with the sides ; disk very 

 moderately convex, two-thirds longer than wide, one-half longer than the 

 head and prothorax together, rather abruptly rounded behind, but some- 

 what acute at the immediate apex ; striae impressed and strongly punctate, 

 becoming obsolete near the tip, except the sutural and exterior with a short 

 auxiliary apical stria; intervals rather convex; punctures round, small, 

 very deeply impressed, rather distant in the series, except in those next to 

 the suture, where they are slightly snialler and closer ; scutellar stria very 

 short, having four or five punctures ; each elytron has at the anterior third 

 a discal puncture in the thii'd striae, and scarcely distinguishable from the 

 others, except that it is setigerous and behind a slightly longer interval, and 

 another at three-fourths the length from the base, very near the third stria ; 

 epipleurae dark rufo-piceous. Legs long and slender ; first joint of the 

 posterior tarsi slightly longer than the next three together, and three times 

 as long as the longest tibial spine. Length 5.5 mm.

Distinguisliable from rnpestre by the much more arcuate sides of 

 the elytra, especially at the humeral angles, and in the total lack of 

 elytral maculation.
